Fairfield Pike |
At-grade intersection | This is the point where 68 widens from two-lane to a four-lane facility. It is also the last non-controlled access intersection until the Champaign County line | |

Cloverleaf | The oddities in this interchange's design show up best in the aerial image linked above. They all appear to have been forced by the local geography and pre-existing street network. | |

Southbound traffic has cloverleaf-style entrance/exit ramps. Northbound traffic has diamond-style ramps. Weird. The other interchange in the photo, 1/4-mile to the east along 334, is with the original US 68 right-of-way |

County Line Road |
Diamond | The limited access portion of 68 used to end here ten years ago. Sometime before August 2005, the 4-lane highway was completed a further half-mile to the northeast to the original RoW. The old highway now ends at a signalled at-grade intersection, after which US 68 reverts to 2 lanes on its old alignment into Urbana. | |
Environmental studies were performed a few years ago on a northward extension of this freeway, passing west of Urbana with interchanges at US 36 and OH 29 before merging back into the existing 2-lane road north of Urbana. The studies must have been favorable, for ODOT will be spending $2.1 million in 2005 to actually design the bypass. Given how low the project keeps scoring against other Miami Valley projects on the TRAC, I can't begin to guess when pavement will be laid.
